Device for the controlled cooling of hot-briquetted, direct-reduced sponge iron

摘要

The invention concerns a device for the controlled cooling of hot-briquetted directly reduced iron sponge, the device taking the form of a plate belt conveyer which is located in a liquid container and comprises individual plates. The individual plate takes the form of a conveyer trough (4), at least one slide plate (5, 6) being disposed in each case on the two opposite longitudinal outer sides, and the conveyor troughs (4) being mounted so as to be displaced by means of the slide plates (5, 6) on slide tracks (7). The conveyor troughs (4) are connected to at least one chain (9). The invention enables the drive and mounting to be separated in that the conveyor troughs (4) are mounted by means of slide plates (5, 6) and the drive in the form of at least one chain (9) acts directly on the conveyor trough (4). Since the translation elements take the form of slide plates (5, 6) and slide tracks (7) the surface pressure is reduced to less than a hundredth in comparison with wheels running on rails. Consequently, the wear of the translation elements is reduced.
